To be honest even for me going from the UK (which was recently known as "plague island") to France is a bit of a gray area, as it's only allowed in very specific cases. I think I'm allowed provided I have all the paperwork but only at the border I'll know for sure, I'm kind of giving it a try basically.
I also need to go into quarantine for 7 days although I think I don't need to go into a hotel since I have my own place.
